CONVEYEB FOR SUBSTANCES IN A FINE 0R LOOSE STATE OF DIVISION.

Application filed May 24,

To all whom it may concern:

Be it known that I, ARNOLD REDLER, of Flour Mills. Sharpness, in the county of Gloucester, England, a subject of theKing of Great Britain and Ireland, have invented certain new and useful Improvements in or Relating to Conveyers for Substances in a Fine or Loose State of Division, of which the following is a specification.

Ihis invention relates to conveyers for substances in a granular flocculent fine or loose state of division.

In conveyers as hitherto made formed of belts of rubber, cotton or similar material Working in a trough, the belt, with or without slats attached, supports and carries the ma terial on the upper run, the belt is distinguished from an open structure in not permitting the material to fall through any opening in the bottom of the trough over which bottom the conveyer travels. In a coal conveyer Where an open link arrangement has been employed the coal is conveyed by the chain which is designed with deep links to form chambers in which the coal lies to the depth of such chambers the links being so deep that the chain could not be pulled through the material in case of the outlet being choked without materially in-' creasing the power or breaking the chain. In conveyers of the creeper type in which the material is drawn along the trough by the bottom of the band to which slats or battens are attached at intervals, the creeper relies on the direct action of the slats to push the material along. In such a conveyer the material cannot fall through the belt itself, but permits any material below it to fall through any aperture in the base of the trough.

In a creeper formed of chain like structure in which both upper and lower runs are in a casing or trough, the slats are generally of large dimensions and far apart, the material being only just in front of each slat and not filling the gap between the links, and does not form an improvised support for conveying theload, moreover should a block occur the slats cannot be drawn through the material without increasingthe power, or risk of breaking the conveyer;

A conveyer made in accordance with this invention comprises a series of links forming a continuous chain-like structure, or a 1921. Serial No. 472,178.

series of battens, bars, slats or the like mounted on or between chains, ropes, links or the like forming a continuous open structure adapted to travel with both upper and lower runs in a closed casing or similar structure of metal, wood, concrete or other suitable material, with or without a division between the upper and lower runs, the link work being of such dimensions and so constructed that it will with the bottom stratum of the substance to be transported when travelling on the surface without apertures, form an improvised solid band on which to carry the remainder of its load. Said link work being of such pitch and width as to allow the substance to drop through when passing over a suitable discharge orifice in the surface over which it is travelling, and is further characterized in that the depth of the transverse bars or slats is small so that when the conveyer is buried in its load it is adapted to slip through the load when the discharge of the load. is checked. If desired either the upper or lower-run can be used as the conveyer portion, or both the upper and lower runs can act as conveyors.

In a conveyer made in accordance with this invention the pitch and width of the links of a chainlike member and the size of the cross bars are of such dimensions that the flour or other substances handled, drops on to the chain and forms a stratum to the depthof the links so that the links with the flour in them form or act as a solid band, supported by the bottom of the trough. I On this improvised band is carried the remainder of the load which can be of considerable depth. When a discharge orifice is reached the bottom stratum, which with the links g has filled the whole of the conveyer thereby preventing the entrance of more flour. The

chain therefore continues its journey with its. links filled with flour until the discharge is freed. The bars of the chains are as small in diameter as possible in order that the minimum poweris required for-the chain to pull itself together with its stratumof flour or other substance through the choked load and also for the purpose of causing the minioverflow discharge;

Fig. 4 is a diagram shewing an application of theinvention for collecting the material from one or more inlets conveying the material by the top run, and delivering through the bottom run the bottom run conterial from entering.

veying surplus material if desired to one or more overflow outlets;

Fig. 5 is a diagram shewing the application of this invention for collecting from two intermediate inlets and discharging at op osite ends.

imilar reference letters are shewn for similar parts in all the figures.

a is a chain like structure composed of a series of wide sprocket links adapted to run on two drums b a each disposed between a pair of sprocket wheels 6 and 0 The sprocket wheel 0 forms the driver and the chain istravelling in the direction shewn by the arrows.

Surrounding the chain is a casing or tube all provided with an opening e for the material to enter and an opening f for the material to be drained off. 9 are scrapers, -h are guides and i a platform.

In operation the substance enters at e and falls through the top run of the chain on to the lower run where it is conveyed to the discharge opening f.

An overflow k may be provided at any point between the inlet 6 and drum 1) and an overflow k anywhere between the discharge f and drum 0.

When the outlet f is blocked the material is discharged through the overflow in. If this is also 'blocked'the surplus material is conveyed by the upper run to parts of the chain not fully loaded and back to overflow is 'until that is blocked, when the materialchokes the inlet 6 and prevents further ma- If desired a platform 11 instead of the .the under run which conveys the material to outlet f, meanwhile another inlet 6 at the other end of the conveyer delivers material onto the platform i so that the upper run conveys it as far as the platform extends, which is between inlet e and outlet f, the material thus dropping through the upper run on to the lower run and through the outlet f.

In F 4 three inlets e e e are shewn. The material is conveyed by the upper run and discharged at f through the lower run, one or more overflow discharges k may be provided, scrapers g 9 being provided at each end. V

In Fig. 5 two intermediateinlets e e are provided, the inlet e delifvers on to the upper run and discharges at f the inlet 6 delivers through the upper run on to the lower run and discharges at f.

If desired a series of sprocket. chains disposed side by side may be connected together by bars or the like at intervals.

The slats or rods may be very small in diameter say about 3 inch and fairly close together, say about 4" apart. 71th a conveyer made in accordance with this invention the flour or other substances may be piled up on the conveyer a foot or more high and moved at 'a low speed, say for instance a foot or so a minute but any suitable speed may be employed.

It will thus be seen that a conveyer made in accordance with this invention is of great capacity, gentle in action and requires the minimum of power whilst it is practically unchokable. Itis suitable for flour, grain, Wheaten products in all stages of manufacture also for numerous other substances such as cement, gravel, sawdust etc.

What I claim and desire to secure by Letters Patent is:-

A conveyer chain for the purpose de scribed, consisting of a plurality of pivotally connected links, each of said links having a pair .of side membersand 'a .transverse member, said transverse member lying wholly within the space between said links and thereby constituting a conveyer flight, the links throughout the chain being of uniform height and thetranverse member similarly being of uniform height, said transverse members having their heights so proportioned with respect to the distance from center to by a ribbon throu h t e material.

In testimony w ereofname to this specification.

ARNOLD REDLER.
